There is a close relationship between problem management and the major incident process. An incident is any event that is not part of the standard operation of a service and that causes an interruption or a reduction in the quality of that service. Incidents are recorded in a standardized system which is used for documenting and tracking outages and disruptions. A Major Incident is an unplanned or temporary interruption of service with severe negative consequences. Examples are outages involving core infrastructure equipment/services that affect a significant customer base, such as isolation of a company site, which is considered a Major Incident.
